At first glance, Ron Arad's designer bike looks like a typical unusable art piece. However, the bike is actually completely rideable and up for auction by the Elton John AIDS Foundation. 18 strips of steel are attached together to form flower-like wheels that roll with tension. Guests at the W Hotel in Leicester Square, London are able to test it out from now until October 29th. (*nudge* *nudge* Grab a video, I'd love to see it in action.)
